Concept of Thermal map (thermodynamics diagram)
Displays an illustration of the page area that the visitor is passionate about or the geographic area where the visitor is located, in a special highlighted form.
Heat force is usually used in the analysis of point data, but many times we do not have point data, only the administrative region data, at this time how we do the analysis of the Heat force diagram.
Raw Data Preparation:
(1) Create a new population density field, field name: Density.
density=[population]/[Shape_area]
(2) Create a grid map of administrative divisions
(3) Select the grid that intersects the administrative region by selecting the location and export it to a new grid.
(4) The population data and the extracted grids for identity analysis.
(5) New population field, field name: Pop, used to store the population of the cells that identify the split after the analysis, and note that the Shape_area field needs to be updated.
(6) Summarize the population data in the cell grid with the ID number of the grid.
(7) Association
(8) Result: Distribute population to each grid.
(9) Visualization of data
